Springy FX v1.0: Bringing Dynamic Secondary Motion to After Effects
In the world of motion design, the difference between a static, rigid animation and one that feels "alive" often comes down to the application of classic animation principles like overlapping action, follow-through, and squash and stretch. While professional animators have used these techniques for decades to breathe life into characters, recreating them manually in Adobe After Effects can be a tedious, time-consuming process involving complex expressions and endless keyframing.
Springy FX v1.0, a toolset created by French motion designer Matthew Frimmo (Frimmox), was developed specifically to solve this problem. It is the first dedicated toolset for After Effects entirely focused on automating "jiggling" secondary motion. What is Springy FX?
Springy FX is a collection of nine tools designed to add elastic, jiggling delays and physical weight to your layers based on their existing keyframed transform properties. Instead of manually animating every subtle vibration, you simply select a layer with movement and apply one of the script's tools to generate automatic secondary motion.
The toolset is available via aescripts + aeplugins and is popular for creating cartoonish aesthetics or adding subtle realism to motion graphics. Core Features and Tools
The version 1.0 toolset consists of nine distinct buttons that can be organized in a horizontal or vertical UI layout: 1. Springy Parent Constraint
This powerful tool allows you to link the movement of one object to another with a springy delay. It is frequently used for complex setups, such as creating a dynamic rope or chain where one end follows a parent with realistic physical inertia. 2. Seven Jiggling Deformers
These tools apply physical deformations to solids, footage, or pre-compositions based on their position or scale animation:
Bend & Shear: Adds a "whippy" or leaning effect to layers as they move sideways.
Squash & Stretch: Automatically compresses and elongates layers based on their velocity. Jiggle: Adds a general "wobble" to the layer’s shape. Springy FX v1.0
Bulge & Twist: Distorts the layer during scaling or rotation, making it feel like a soft body (e.g., a "pillow" shape during rescaling).
Liquid: Creates a fluid-like trailing effect for moving layers. 3. Custom Effect
A versatile tool that allows advanced users to apply springy behaviors to custom parameters, providing even more control over the physics of the animation. How to Use Springy FX v1.0
The script is designed for a "one-click" workflow that remains non-destructive:
Animate your layer: Apply standard keyframes to the position, scale, or rotation of a layer.
Apply a tool: Select the layer and click one of the Springy FX icons (e.g., the Bend tool).
Adjust the controls: The script automatically generates a "spring constraint control" layer. This layer contains sliders to fine-tune the elasticity, damping, and offset of the effect.
Note: Because of how the deformations are calculated, the script works best on solids, footage, and pre-comps rather than raw Shape or Text layers, which may need to be pre-composed first for optimal results. Why Use Springy FX?
Speed: What would take hours of manual expression-writing or keyframing can be achieved in seconds. Springy FX v1
Physical Realism: It helps motion graphics convey a sense of weight and mass, which is often missing in digital animation.
Flexibility: You can combine multiple deformers on a single layer—for example, adding a Bend effect on top of a Bulge effect—and control them from a single UI. Springy FX - aescripts.com
Springy FX v1.0 is an After Effects extension by Fremox designed to automate secondary motion—such as jiggling, overlapping, and "squash and stretch"—based on existing keyframed transform properties. The toolset includes nine distinct tools, such as Parent Constraint, Bend, and Liquid, which allow for customizable physics control through a dedicated "Spring Constraint CTRL" layer.
